ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 459,553, datedSeptember 15, 1891.

Application filed March 12, 1 8 91.

To all whom it may concern.-

Be it known that I, HOOKER SHAPEL, a citizen of the United States,residing at Iola, in the county of Allen and State of Kansas, haveinvented a new and useful Ice-Cream Freezer, of which the following is aspecification.

This invention relates to improvements in that class of ice-creamfreezers in which a refrigerating revoluble cylinder and scrapingdelivery-blades are employed; and the objects in view are to provide amachine of cheap and simple construction adapted for easy operation andfor the manufacture and delivery of one or a series of different flavorsof cream, as will be desired.

WVith the above main objects in view the invention consists incertainfeatures of construction hereinafter specified, and particularlypointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of an ice-creamfreezer constructed in accordance with my invention. Fig. 2 is avertical longitudinal section. Fig. 3 is a transverse section. Fig. 4.is a detail in perspective of the refrigerating-cylinder. Fig. 5 is aperspective of the casing, the same being opened. Fig. 6 is a detail inperspective of one of the cream-receiving trays and its deliveryscraping-blades.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I employ a casing or box consisting ofopposite side pieces 1, the front edges of which are inclined and therear edges of which are curved, a rear wall 2, curved to conform totheedges of the side pieces, a bottom 3, and a front wall 4, the latterhaving a sight-panel 5, of glass, hinged at its lower edge to the frontedge of the bottom, as at 6, an ordinary spring-bolt 7 being secured tothe upper edge of the front wall and adapted to engage with the keeper8, whereby said wall may be maintained in a locked position. Theopposite side walls of the casing are covered with a sheet-1netallining9, and the lower edges of the same are curved or semicircular andconnected by a curved bottom 10, the pieces 9 and 10 forming a curvedtank, as shown.

11 designates the cover of the casing, the same also being-lined withsheet metal, as at 12,

Serial No. 384,817. (No model.)

hinged at its rear edge to the rear edge of the casing, as at 13, andlimited in its rearward movement by a strap 14;. By the inclinationgiven the front edges of the side walls 1 of the casing there is formedin front of the sheet-metal tank therein a space or compartment l-l,preferably provided with aremovable tray l5,covered by agrating 16,adapted to receive and support saucers or other vessels placed there forthe purpose of receiving the ice-cream as the same is manufactured, in amanner hereinafter specified.

17 designates a cream-receiving tray, of which there is preferably aseries, each consisting of a curved bottom 18 and opposite side walls19, the latter having their upper edges cut out or recessed, as shown.The front ends'of the side walls extend slightly beyond thecorresponding ends of the bottoms of the trays, and to said side wallsby means of pairs of straps 20 there are connected a series of combinedscrapers and delivery-blades. Each .of these combined scrapers anddelivery-' blades consists of an inclined bottom wall 21, the upper edgeof which is straight to form a scraping-edge, and opposite side walls22, the latter converging toward their lower ends, so .as to properlydeliver the frozen cream as the same is manufactured. These series ofcream receptacles have their side walls near their rear ends perforated,as at 23, and through the entire series passes a rod 24, one end ofwhich is inserted in a socket or bearing 25 and the other end of whichrests in a halfbearing 27, said bearings being located upon the oppositeend walls of the casing and the half-bearing covered by a turn-button28. When the rod is in position through the series of crea1n-receivingpans and the button turned to lock the bearing, said pans remainundisturbed by the operationsof the machine, as hereinafter explained,and can only heremoved by the partial rotation of the turnbutton, thesubsequent lifting of that end of the rod that rests within thehalf-bearing, and finally the removal of the rod and series of pans-Each pan is also provided with an opening 29 in its rear end, andthrough the same pass tubes 30, which also pass through the rear wall ofthe casing and terminate in funnels 81, all of which are located in areceiving compartment or case 32 and covered by a lid 33, hingedthereto.

34 designates a series of cylinders, formed of sheet metal and connectedby short. cylindrical collars 35, of a lesser diameter than are thecylinders, the heads of the cylinders being open, so as to affordcommunication throughout the series. The head of each cylinder iscomposed, of two circular layers of sheet metal 36, between which areinterposed suitable non-conducting packings 37. The outer head of one ofthe outer cylinders is provided with a hollow-bearing trunnion 38, uponwhich is screwed a cap 39, and the latter is provided with a smallperforation 40, upon which is screwed a smaller cap 41. Through themedium of the larger cap the refrigerating agent may be inserted, andthe smaller cap may be removed for the purpose of pouring the melted icetherefrom.

Each of the cylinders is provided with a series of shelves 42, locatedtherein and extending transverselyacross the inner peripheries orsurfaces of the cylinders from head to head. These shelves are for thepurpose of engaging and carrying the refrigerative agent during aportion of the rotations of the cylinders. Each cylinder is of a widthto fit between the side walls of a cream-receivingtray, the collarsconnecting the cylinders serving to span the spaces between the trays.The outer end of that outer cylinder opposite the one heretoforedescribed as having the threaded caps and hollow trunnion is providedwith a stub axle or shaft 43, said hollow trunnion and shaft beingdesigned to locate in bearings 44 and 45, respectively, the halves ofwhich are formed in the meeting edges of the casing and the cover. Thestubshaft carries at its outer end a gear 48, which is engaged anddriven by a small pinion 49, located upon a stub-shaft 50, extendingfrom the end Wall of the cover and operated by a crank-handle 51. Aseries of-iu this instance threebearing-standards 52 is located upon thecurved bottom of the tank of the casing, and as many shafts 53 arejournaled in the standards and in one of the end walls of the casing,each of said shafts being provided between its bearings with a crankedportion 54, upon which is mounted a loose roller 55, and at its outerend with a handle 56, by means of which said shafts may be partiallyrotated, and thus the cream-pans raised or lowered so as to bring anyone or all of the scraping-blades thereof into contact with theperiphery of the refrigerating-cylinders.

This being the construction, the operation is as follows: By removingthe screw-cap from the hollow trunnion of the cylinder crushed ice orother refrigerative agentis introduced,

and with the same each cylinder is either Wholly or partially filled,after which the cap is replaced and the cylinder mounted in itsbearings. The lid is now closed and receptacles placed in thecompartment at the front end of the casing for the reception. of thefrozen cream, which latter is now introduced in liquid form by beingpoured into the funnels at the rear side of the casing and passed fromthem into the cream-receiving pans. It is designed to employ a series ofcylinders, as shown in the present instance, and the pans of the samereceive creams of various flavorings.

If it is desired to freeze a saucer'of each of the three flavors, eachof the handles of the cranked shafts under the pans is turned so as tothrowthe cranked portions up, and, as the front ends of the pans restthereon said front ends are also carried up, the pans swinging upon thepivotal rod passed through their rear ends. Such movement upon the partof the cranked shafts brings the upper scraping-edges of the severalscrapers into contact with the peripheries of their respect ivecylinders. It. now simply remains to rorate the crank of the stub-shaft,and through the medium of the pinion of the latter the large gear of thecylinder, together with the cylinder, is rotated from rear to front, and

the cream adhering to the periphery of the cylinders as they areimmersed therein is congealed or frozen by contact with the surface ofthe cylinde r and is scraped by the combined scrapers anddelivery-blades from the outer peripheries of the cylinders andsubsequently delivered into saucers or other ice-cream-receivingvessels. In this manner as much cream as may be desired to meet thedemands may be instantly manufactured, and that, too, of several flavorswhen so desired. By merely manipulating one of the crankshafts any oneof the various flavors may be manufactured, the scrapers of theremaining flavors remaining out-of contact with the cylinders.
